Stages of Interphase<\/h2>\n

During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase.\u00a0 In order for a cell to move from interphase into the mitotic phase, many internal and external conditions must be met.<\/p>\n

The three stages of interphase are called G1<\/sub>, S, and G2<\/sub>.<\/p>\n

G1<\/sub> Phase (First Gap)<\/h3>\n

The first stage of interphase is called the\u00a0G1<\/sub> phase<\/strong> (first gap) where the cell is quite active at the biochemical level. The cell is accumulating the building blocks of chromosomal DNA and the associated proteins as well as accumulating sufficient energy reserves to complete the task of replicating each chromosome in the nucleus.<\/p>\n

S Phase (Synthesis of DNA)<\/h3>\n

In the\u00a0S phase<\/strong>, DNA replication<\/span> results in the formation of identical pairs of DNA molecules\u2014sister chromatids\u2014that are firmly attached to the centromeric region.<\/p>\n

G2<\/sub> Phase (Second Gap)<\/h3>\n

In the\u00a0G2<\/sub> phase<\/strong>, the cell replenishes its energy stores and synthesizes proteins necessary for chromosome manipulation. Some cell organelles are duplicated, and the cytoskeleton is dismantled to provide resources for the mitotic phase.<\/p>\n\n\t\t\t
